Application filed February 12, 1917. Serial No. 147,994. 7

To all whom it may concern Be it known that I, CORNELIUS Gianna subjectof the King. of Great Britain and Ireland, and residing at 12 Taskerstreet,

have invented an Improved and Useful ing is a specification.

This inventlon relates to improvements 1n object to provide an improveddevice of'the slotted bar and turn-button formof such fastener. I

According to this my invention the stair carpet fastener comprises arail orbar of any suitable section notched at one orboth ends. Eachnotch is adapted to receive a support which prevents lateral movement ofthe notched end of the rail orrod when the said pillar part is in place.Attached to the said support, so that it can be moved about its axis, isan arm adapted to engage a notched endof-the rail or bar to prevent itsmovement axially of the said support. ,Provision is made for preventingthe movement of the arm axially of its support andalso for securing thesaid'supp'ort in place. 7

In the accompanying drawings, which illustrate one form of this myinvention,

Figure 1 is a part front view of a stair carpet fastener made inaccordance with this invention, and l i Fig. 2 is a part plan thereof.

This embodiment of my invention is shown as comprising three parts, arail or bar a a1id two supports 6, b." The rail .or bar a is' employedtohold the stair carpet at the foot of a stair-riser in place of the wellQ p 0 of said rod, aplllar adapted to engage each known rod. The flatrail or bar a, when in place is parallel to the face of theriser and v I.trensversely thereof, a rotatable arm pivotedaxially upon said pillarand adapted to prevent movement of said rod axially is retained inposition there by means of swinging arms 0, 0, each carried by a short(Z.

preferably on the riser as shown in Fig. 1, each pillar d is providedwith a flange it having holes through which screws may be driven intothe said riser.

When the stair carpet is in place itis retained in position behind therail orbaro,

prevented from releasing it by the arms c, c,

which then occupy the positions shown on the riglithancl side of Fig. 1,and'in broken I lines in Fig. 2. The carpet is thus not liable Walsall,in the county of Staiford, England,
